South Korean mobile phone maker Samsung has already enjoyed increased success with its Galaxy S and Galaxy Note series of mobile phones.

According to the latest rumor from mobile gossip site SamMobile, Samsung is planning to launch a series of new big-screen devices which don’t fit into its high-end Galaxy Note family, and will instead create a new range called the Galaxy Mega.

No official confirmation on the matter has emerged, but it seems that Samsung might unveil at least two handsets in the new series.

One of them might be GT-I9152, expected to be launched as Galaxy Mega 5.8, while the other would be GT-I9200, set to hit shelves as Galaxy Mega 6.3, each featuring the screen size mentioned in the name.

They’re both rumored to arrive in late May or early June; but for now, they remain distinctly unofficial.
